This is an HO scale model of Philadelphia and Reading railroad GAc gondola. Regarding the prototype, 1500 of these early steel gondola cars were built for the Philadelphia & Reading RR in 1901 to 1902 by the Cambria Steel Company. Their claim to fame was a 50-ton capacity and the use of standard structural steel shapes, meaning that spare parts could be purchased from any commercial steel shapes supplier. These cars ran as built until 1909 when they began to be rebuilt with fishbelly side sills, new end sills, & steel braced ends.
